Fixes #132692. `clang -cc1` crashes when generating a module interface with `emit-module-interface` or `emit-reduced-module-interface` using an input file which is already a precompiled module (`.pcm`) file. This commit adds validation for the input file format and Clang will now emit an error message instead of crashing.
